"Neoceader" contains nicotine. A report of two user's nicotine addiction

"Neoceader smoking" is widely marketed in drug stores as an over the counter expectorant for cigarette smokers in Japan. Using high-pressure liquid chromatography, we determined that one piece of Neoceader (3 cm) contains 0.79 mg of nicotine, which is equivalent to one-sixth of the amount of nicotine in one Japanese cigarette (Mildseven extra-light, Mildseven super-light, or Sevenstar). Two patients who had switched from cigarette smoking to Neoceader smoking, subsequently became addicted to nicotine. The continine concentration in their urine were 937 ng/ml and 2,724 ng/ml, respectively. These findings demonstrate that Neoceader contains nicotine and that its use can lead to nicotine addiction.     

Exploring children's conceptions of smoking addiction.

Tobacco addiction is a major health problem for both adults and young people--between 20 and 60% of adolescents are dependent on nicotine and more than two-thirds who attempt to quit experience withdrawal symptoms. Yet, anti-smoking efforts targeted at children emphasize primary prevention and ignore addiction education, which is generally considered relevant only to adult smoking and cessation efforts. This study reports children's concepts of smoking and addiction from interviews with 32 Western Australian boys and girls, aged 9-10 years, all non-smokers. Results suggest children's concepts of smoking addiction may influence attitudes toward smoking trials. Children who thought addiction happened immediately were committed to never smoke at all. Others who thought addiction happened after several cigarettes expressed intentions to experiment. These children believed they could avoid addiction by smoking less than the number of cigarettes that caused addiction. Children who defined addiction as 'liking' or 'enjoying the taste of cigarettes' believed they could avoid being 'hooked' as long as they managed to avoid enjoying the experience. Recent findings that children can get 'hooked' within a few days of smoking highlight the importance of addiction strategies targeted at children, particularly in relation to influencing intentions to experiment with smoking.     

Kicking the habit is hard: A hybrid choice model investigation into the role of addiction in smoking behavior

Use of choice models is growing rapidly in tobacco research. These models are being used to answer key policy questions. However, certain aspects of smokers' choice behavior are not well understood. One such feature is addiction. Here, we address this issue by modeling data from a choice experiment on the US smokers. We model addiction using a latent variable. We use this latent variable to understand the relationship between choices and addiction, giving attention to nicotine levels. We find that more addicted smokers have stronger preferences for cigarettes and are unwilling to switch to e‐cigarettes. Addicted smokers value nicotine in tobacco products to a much greater extent than those that are less addicted. Lastly, we forecast short‐term responses to lowering nicotine levels in cigarettes. The results suggest that current nicotine‐focused policies could be effective at encouraging addicted smokers to less harmful products and lead to substantial public health gains.     

Anxious adults vs. cool children: children's views on smoking and addiction

Tobacco addiction represents a major public health problem, and most addicted smokers take up the habit during adolescence. We need to know why. With the aim of gaining a better understanding of the meanings smoking and tobacco addiction hold for young people, 85 focused interviews were conducted with adolescent children from economically deprived areas of Northern Ireland. Through adopting a qualitative approach within the community rather than the school context, the adolescent children were given the opportunity to freely express their views in confidence. Children seem to differentiate conceptually between child smoking and adult smoking. Whereas adults smoke to cope with life and are thus perceived by children as lacking control over their consumption, child smoking is motivated by attempts to achieve the status of cool and hard, and to gain group membership. Adults have personal reasons for smoking, while child smoking is profoundly social. Adults are perceived as dependent on nicotine, and addiction is at the core of the children's understanding of adult smoking. Child smoking, on the other hand, is seen as oriented around social relations so that addiction is less relevant. These ideas leave young people vulnerable to nicotine addiction. It is clearly important that health promotion efforts seek to understand and take into account the actions of children within the context of their own world-view to secure their health.     

Quit attempts among African American teenage smokers seeking treatment: gender differences

BACKGROUND: African Americans experience disproportionate smoking-related mortality. Because established smoking during youth predisposes to adult smoking and serious health consequences, characterizing ethnic differences in adolescent smokers' self-quit attempts may inform ethnic-specific approaches to youth smoking cessation. METHODS: African American and European American teenage smokers applying to a teenage smoking cessation study (2000-2003) provided smoking-related data, including characteristics of previous cessation attempts and prior use of nicotine replacement therapy (NRT). Tobacco dependence was assessed using the Fagerstrom Test of Nicotine Dependence (FTND). RESULTS: Of 980 (15.5 +/- 1.3 years, 41.8% African American, 59.9% female) participants, African Americans boys were significantly less likely than European American boys to report a prior quit attempt (OR = 0.35, 95% CI 0.17-0.73, P = 0.0049) or to have used NRT (OR = 0.60, 95% CI 0.36-0.998, P = 0.049) after adjusting for years smoked and FTND score. African American girls were more likely to report a prior request for cessation treatment than European American girls after adjusting for FTND and years smoked (OR = 2.19, 95% CI 1.37-3.48, P = 0.001). CONCLUSIONS: While increasing education and outreach to African American boys and enhancing access to formal cessation programs for African American girls who smoke may be beneficial, our findings warrant extension to non-treatment-seeking teenage smokers.     

Tobacco harm reduction and the evolution of nicotine dependence

In recent years, a renewed debate has developed around the potential for modified tobacco products to play a role in reducing tobacco-related harm. During the 1960s and 1970s medical experts recommended to smokers who could not quit that they switch to cigarettes with lower tar and nicotine content. At the time, survey data suggested that smokers who switched did not compensate for the reduction in nicotine by increasing their intake. However, public health scientists were hindered in their ability to evaluate the population impact of the reduced tar strategy by a limited understanding of nicotine addiction. Smoking dependence was seen as primarily psychological and social, rather than pharmacological or biological, until the late 1970s, when addiction researchers began to apply experimental techniques from other forms of drug abuse to study smoking behavior. This history has important lessons for current discussions about tobacco harm reduction and regulation of nicotine delivery.     

Adolescent Obesity as a Risk Factor for High-Level Nicotine Addiction in Young Women

Purpose

Obesity and cigarette smoking are two of the most frequent and preventable causes of disease and death in the United States; both are often established during youth. We hypothesized that obese, adolescent girls would be at higher risk for nicotine addiction in young adulthood, and that particular individual and social factors would mediate this association.

Methods

Students surveyed in the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative school-based and in-home survey conducted in three waves, comprised the sample. More than 4,000 respondents were used for the multivariate linear and logistic regression analyses used to determine the association between obesity and level of nicotine addiction. Potential mediation effects of the association were also examined.

Results

Obesity doubled the risk of the highest level of nicotine addiction after controlling for demographic factors, parent and friend smoking, and baseline smoking (OR, 2.12; 95% CI, 1.22–3.68). Family smoking was the strongest predictor of nicotine addiction (OR, 4.72; 95% CI, 2.89–7.72). Grade point average was a partial mediator of this relationship (OR, .48; 95% CI, .32–.74).

Conclusions

Obese, adolescent females are at increased risk for high-level nicotine addiction in young adulthood as compared with their nonobese peers. Grade point average partially mediates the association, and may represent a confluence of factors including increased absenteeism, social marginalization, biases, and lack of confidence in academic ability. Obese, adolescent females may require targeted interventions to address their risk of subsequent high-level nicotine addiction, especially if risk factors such as parental smoking and poor school performance are present.     

An 18-month follow-up study on the influence of smoking on blood antioxidant status of teenage girls in comparison with adult male smokers in Korea

OBJECTIVES: The influence of cigarette smoking on blood antioxidant status in teenage girls with a history of short-term smoking was followed over 18 mo. METHODS: Data obtained from female senior high school students (ages 14 to 18 y) in Korea were compared with data obtained from adult male smokers (ages 36 to 51 y) with a long history of smoking and living in the same geographic areas as the teenage subjects. A smoker was a person who had smoked at least three cigarettes a day for at least 1 y for teenagers (n = 35) or at least 10 cigarettes a day for at least 13 y for adults (n = 20). Serum, urine, and anthropometric data were obtained from teenagers every 6 mo over an 18-mo period. Samples were collected once from adults. Data were analyzed by Student's t test and Fisher's protected least significant difference test for comparing smokers and non-smokers and for analyzing period effects in each group. RESULTS: Serum nicotine and cotinine concentrations were higher in smokers than in non-smokers. Blood pressures were higher in teenage (at 0 and 12 mo) and adult smokers than in non-smokers. Extracellular superoxide dismutase activities and concentrations of serum vitamin C and folate were lower in smokers in the teenage (at 0, 12, or 18 mo) and adult groups. Serum ceruloplasmin activities and thiobarbituric acid-reactive substance production were not influenced by smoking. In adults, serum copper concentrations were higher in smokers than in non-smokers. This parameter for teenagers did not change consistently throughout the study. CONCLUSIONS: Similar to adults, cigarette smoking by teenagers has a negative effect on oxidant defense systems.     

Ambivalence and uncertainty: experiences of and attitudes towards addiction and smoking cessation in the mid-to-late teens

The late teens is an important transitional period as adolescents move into new social worlds which support or challenge their smoking. This paper draws on research with 99 Scottish 16- to 19-year olds which explored their understanding of their smoking and attitudes towards quitting and cessation support. The study involved qualitative interviews mostly with friendship pairs. Interviewees also completed a brief smoking questionnaire. Most regarded themselves as smokers but few thought they were addicted. Many were interested in quitting but this was not a priority. Perceived barriers to quitting related primarily to habitual and social aspects of dependence including friends' smoking, the smoking culture at work or college, stress and boredom. Few were interested in nicotine replacement therapy or cessation services, which they felt belonged to the world of older addicted smokers. The most effective quitting strategy was thought to be will-power. Traditional cessation services are therefore in their current form unlikely to appeal to older adolescents. Services aimed at this age group need to be grounded in their understandings of smoking and the social factors which support smoking. Young smokers should also be helped to understand how support may increase quitting success and how encourage quitting before smoking becomes entrenched in their daily routines.     

Maternal Prenatal Depressive Symptoms, Nicotine Addiction, and Smoking-Related Knowledge, Attitudes, Beliefs, and Behaviors

Maternal smoking is a key preventable cause of poor pregnancy outcomes, such as low birthweight. In many areas of the United States, including Eastern North Carolina, rates of prenatal smoking are high. Prenatal depressive symptoms are associated with maternal smoking, but there remains much to learn about this relationship, especially among Black women, who have double the risk of poor pregnancy outcomes of White women. In the study reported in this paper, we investigated the relationship between maternal prenatal depressive symptoms with smoking behaviors, beliefs and attitudes, environmental factors which promote smoking and nicotine addiction. Pregnant women were enrolled in the study at the first prenatal visit to the clinics of the Departments of Obstetrics and Gynecology and Family Medicine of the Brody School of Medicine, East Carolina University. An interviewer administered a questionnaire to each woman about smoking, smoking-related attitudes, knowledge, beliefs and behaviors, nicotine addiction, and home environmental factors that encourage smoking. The CES-D was used to measure depressive symptoms. We used the cut-point score of 23 or greater to indicate elevated depressive symptoms, which is thought to represent major depressive disorder. The sample consisted of 810 Black women, of whom 18% were smokers. CES-D score was associated with nicotine addiction, not thinking of quitting smoking, and not expecting support from family and friends if they decided to quit. Prenatal depressive symptoms may be a barrier to smoking cessation.     

Smoking and weight control in teenagers

In a Cancer Research Campaign-funded survey of smoking habits and opinions of 16,000students aged 9–19 years in northern England in December 1982, the respondents were asked if they thought that smoking keeps the weight down.The heaviest regular smokers (42·2%) were the most likely to agree that smokingcontrols weight, whilst those who had never smoked were least likely to agree (16·6%). Agreement increased with increasing smoking. More girls than boys agreed. The most significant differences between smokers' and non-smokers' opinions occurred in 13-, 14- and 16-year-old girls. In this age group more girls than boys reported regular smoking. Up to the age of 12 years, smokers were extremely unlikely to agree that smoking keeps the weight down.It is suggested that the intention of weight control might be influential in causing the high incidence of smoking in teenage girls.     

“Cloud chasers” and “substitutes”: e‐cigarettes,vaping subcultures and vaper identities

The use of e‐cigarettes is increasing, a practice denoted as vaping. We explore user motives, self‐identity as vapers and involvement in vaping subcultures, drawing on sociological theory of stigma, subcultures and symbolic boundaries. Based on analyses of semi‐structured interviews with 30 Norwegian vapers, we find that there is a vaping subculture in Norway. We identify two dominant vaper identities. The first is labelled cloud chasers. These were dedicated vapers who identified with symbols and values in the subculture. Many were politically engaged in improving vaping regulation regimes and felt a sense of belonging to a vaping community. The second group is labelled substitutes. These were former daily smokers who used e‐cigarettes for smoking cessation in a more pragmatic and defensive manner, to avoid health risks, to escape the stigma of smoking and to manage nicotine addiction. In this group, self‐identity as a vaper was generally lacking. Vaping was often symbolically linked to the stigmatised smoker identity they wanted to escape, and was restricted to private contexts. The perceived symbolic meaning of e‐cigarettes varies: for some, they are a symbol of pleasure and community. For others, they connote the stigmatised status of the addicted smoker seeking an alternative to cigarettes.

Initiation of cigarette smoking and subsequent smoking behavior among U.S. high school students

BACKGROUND: Most adult smokers report trying their first cigarette before age 18 years. Understanding the impact of smoking initiation at young ages may help public health policy makers and practitioners improve strategies to prevent or delay adolescent cigarette smoking. METHODS: This paper examined age of initiation of cigarette smoking and subsequent patterns of smoking among U.S. high school students 16 years of age and older (N = 13,858). We used data from the 1991-1997 national Youth Risk Behavior Surveys, conducted by the Centers for Disease Control and Prevention. RESULTS: The majority of students 16 years of age and older (60.4%) reported ever having smoked a whole cigarette, and 11.1% initiated smoking at age 10 years or younger. Age of smoking initiation was significantly related to current frequent smoking, daily smoking, and whether students had ever smoked daily. A younger age of smoking initiation was associated with smoking more cigarettes per day than was initiating at an older age. CONCLUSIONS: Delaying the onset of smoking may affect the likelihood of becoming addicted to nicotine and smoking heavily. For students who are already addicted to nicotine, smoking cessation programs are needed.     

The AMA proposal to mandate nicotine reduction in cigarettes: a simulation of the population health impacts

BACKGROUND: The American Medical Association (AMA) has advocated gradually reducing the nicotine content of cigarettes to decrease smoking prevalence. Some experts have voiced concerns that smokers may "compensate" by smoking more cigarettes or inhaling more deeply. Further, a black market may emerge, perpetuating cigarette availability. Thus, it is unclear whether a federal mandate would result in a net increase or decrease in population health. The purpose of this research is to estimate the long-term health gains or losses that are likely to accrue to the US population if the nicotine content of cigarettes is gradually reduced to trace levels over a 6-year period. METHODS: To estimate health impacts, we created the Tobacco Policy Model, a computer simulation model. The model simulates the US population as they age and change their smoking behavior over time. Secondary data for model parameters were obtained from publicly available sources. Population health impacts were measured as the change in cumulative quality-adjusted life-years (QALYs) in the US population over 50 years. RESULTS: Following a mandate to reduce nicotine, smoking prevalence is likely to decline from 23% to 5% of the population. Accordingly, a cumulative gain of 157 million QALYs is expected over 50 years. CONCLUSIONS: Despite any mortality increases due to compensatory smoking or the emergence of a black market, implementation of the AMA proposal would likely prevent the addiction of scores of new smokers and result in important gains to the nation's health. This research should prove useful to Congress as they contemplate giving the FDA the authority to regulate tobacco.     

Teenage smoking and antecedent parentalcharacteristics: A prospective study

The smoking habits of 1445 white adolescents aged 15 to 17 years were examined in relation to 16 characteristics of the family prevailing at the time the mother was pregnant with the child. Five characteristics were independently associated with teenage smoking, either for boys or girls or both: parental smoking, mother's education and age, father's education and occupation.Multiple regression showed that father's occupation was redundant for both boys andgirls, and that mother's education was redundant for boys' smoking. Parental smoking, father's education and mother's age each had predictive power for boys' smoking. For the girls, mother's education also had predictive power. In general, the major family characteristics associated at birth with later teenage smoking are parental smoking habits and socioeconomic status. The sex differences between associations of family characteristics and teenage smoking suggest that the like-sexed parents' smoking and education have the greater effect on teenage smoking, particularly for the boys. For girls, present smoking status of mother was of more importance than mother's smoking status at birth if the mother had given up smoking.     

Counselling teenage girls on problems related to the 'protection of family honour' from the perspective of school nurses and counsellors

Approximately 1,500 young immigrant women living in Sweden sought help from various public organisations during 2004 due to problems related to Protection of Family Honour (PFH). Often they seek help from school nurses and counsellors. Information on how the school nurses and counsellors manage this complex PFH phenomenon is limited in Sweden. The aim was to generate a theoretical model that illuminates the experiences of school counsellors and school nurses counselling teenage girls, who worry about problems related to protection of family honour. Data were collected through individual interviews of the school welfare staff. The study subjects included welfare staff from six upper-secondary schools consisting of four nurses and six counsellors. Grounded theory methods were used to generate new knowledge as this is a new field of research. The staff's main goal was to provide the best support and help for the teenage girls. In addition, they wanted to be true to their professional ethics and values. However, this was difficult and created professional dilemmas because some teenage girls prevented them from doing what they thought was needed to support the teenage girls and protect them from violence. As a result, staff sometimes felt hampered, unable to help or able to help only in ways hidden from the teenage girls' families.     

'Light' and 'mild' cigarettes: who smokes them? Are they being misled?

Using two population-based surveys of Ontarians, we examined the proportions of smokers who smoke 'light' and 'mild' cigarettes (L/M). We compared L/M smokers to regular cigarette smokers regarding demographic, health knowledge, and smoking characteristics and examined their health-related perceptions of L/M and reasons for smoking them. Use of these cigarettes increased from 71% in 1996 to 83% in 2000. Those who smoked L/M were more likely to be female, to be less addicted, and to be more advanced toward quitting. In 1996, one in five believed that smoking L/M lowers the risk of cancer and heart disease. In 1996 and 2000, respectively, 44% and 27% smoked L/M to reduce health risks, 41% and 40% smoked them as a step toward quitting, and 41% in both years said they would be more likely to quit if they learned L/M could provide the same tar and nicotine as regular cigarettes. These data provide empirical support for banning 'light' and 'mild' on cigarette packaging.     

Can one puff really make an adolescent addicted to nicotine? A critical review of the literature

Rationale  

In the past decade, there have been various attempts to understand the initiation and progression of tobacco smoking among adolescents. One line of research on these issues has made strong claims regarding the speed in which adolescents can become physically and mentally addicted to smoking. According to these claims, and in contrast to other models of smoking progression, adolescents can lose autonomy over their smoking behavior after having smoked one puff in their lifetime and never having smoked again, and can become mentally and physically "hooked on nicotine" even if they have never smoked a puff.     

Prenatal smoking cessation among Black and White women in Eastern North Carolina

PURPOSE: Limited information is available about Black:White disparities in prenatal smoking cessation, and the results of prior research are inconsistent. We analyzed smoking cessation and factors associated with cessation (attitudes, environment, and nicotine addiction) in a sample of pregnant Black and White women. METHODS: Women were interviewed at the first prenatal visit at two hospital-based clinics. RESULTS: Among former and current smokers, there were no significant differences in the percentage of former smokers between Black (46.8%) and White (43.3%) pregnant women, or in the percentage of "spontaneous quitters" (i.e., those who quit after learning that they were pregnant) for Blacks (36%) and Whites (28%). Both Black and White spontaneous quitters had evidence of occasional relapses to smoking. For Black and White women, smoking more than a pack a day prior to pregnancy was associated with smoking during pregnancy. DISCUSSION: Among current and former smokers, spontaneous cessation was about the same for Black and White women, and about two thirds of women who were smokers when they learned of the pregnancy continued to smoke during pregnancy. Nicotine addiction contributed to continued smoking.
